WaitForCompletion() not working?

[ahmetteksas]

`[ServerRpc] private void ServerSpawnPlayer() { GameObject playerPrefab = Addressables.LoadAssetAsync<GameObject>("Player").WaitForCompletion();

    GameObject playerInstance = Instantiate(playerPrefab);

    Spawn(playerInstance, Owner);
}`

why is this line red? "Addressables.LoadAssetAsync<GameObject>("Player")"

please do not suggest me the link below because ı wrote same thing on the linked example, everything is the same, nothing changes !. I use 2021.1.6f1 version. Please fix the bug as soon as possible.

As far as I understand, the version of Addressables used in this sample project is not updated to the latest Addressables version. Therefore, it simply doesn't have the WaitForCompletion method available. I tried updating the Addressables version to the latest, and my editor picked up the WaitForCompletion method on the handle.

(This comes with other issues though, I got seemingly unfixable Library compile errors as a consequence)
